blueview (Hong Kong) Industrial Development Co., Ltd. was officially registered in Hong Kong in 2000, and its headquarters are located in Shuangliu Airport Economic Development Park, Sichuan Province. Sichuan blueview optoelectronics is its wholly-owned subsidiary, with a total construction area of 26000 square meters. It is one of the production bases of domestic advertising sign light sources and linear commercial lighting light sources at present. It has 38 offices throughout the country, with marketing networks and after-sales support all over the country

lamps with the same power are much cheaper than. The so-called "one price, one goods", this sentence is not wrong at all. In order to reduce the cost of these low-cost lamps, resistance capacitance step-down circuits are widely used to drive LED beads. The resistance capacitance step-down circuit has a big defect, that is, the circuit will have a certain impact on the lamp bead at the moment of the control switch on and off, which will affect the life of the lamp bead. This kind of drive circuit LED lamp is not suitable for use where it is frequently switched on and off

it is pointed out that the LED spectrum has good monochromaticity, no excess infrared, ultraviolet and other spectra, no harmful substances, and little heat and radiation. 9、 Plane luminescence, strong directivity. It is different from the incandescent lamp with point light source, and the angle of view is ≤ 180 °. When designing, we must pay attention to and make use of the characteristics that the LED light source has different angle of view and cannot be greater than 180 °. 10、 Led belongs to multi compound semiconductor components. The characteristic of multicomponent compound semiconductor components is that their electrical, optical, thermal and mechanical parameters are very discrete

in the development process of more than 10 years, blueview has been focusing on the research and development, process design and production feasibility study of LED products with domestic MDI demand of 226000 tons in 2001. The diversified products with high quality, high-tech content and high added value have obtained more than 80 patents and sold well in more than 140 countries and regions around the world. Over the past 15 years, it has established its position as an industry leader with rapid sales growth, and has been awarded "high tech enterprise" and "Chengdu enterprise technology center" by Sichuan Department of science and technology

however, how to choose depends on the specific configuration of the model and personal needs. At the beginning of the new year, many friends are planning to replace the old lamps at home or decorate their new houses. It's natural to have a practical LED lamp, but how can you choose one that suits you from thousands of brand models? 1、 LED, incandescent lamp and energy-saving lamp cannot be distinguished? Incandescent lamp works on the heating principle of tungsten wire, which is our common round head bulb. Energy saving lamps belong to the category of fluorescent lamps, which emit light by fluorescent powder,

in the process of use, we should also try to reduce the workload of lamps, so as to delay the speed of light decay and prolong the service life of lamps. The correct installation of indoor lamps and lanterns is the premise of prolonging the service life of lamps and lanterns. If the installation is not correct, the lamps are easy to break down, sometimes even burst, short circuit and fire are very dangerous. For example, the lamps in the bathroom must be equipped with moisture-proof lamps, and the lamps in the kitchen should pay special attention to the prevention of lampblack and water vapor. Attention should be paid to the use of indoor lamps and lanterns in the family, and do not turn them on and off frequently, because the current passing through the light source at the moment when the lamps and lanterns are used to measure the hardness value of products that are not suitable for disassembly or larger and are frequently started is greater than the current during normal work

blueview optoelectronics once occupied 1/4 of the market share of industrial and commercial logo light source projects, and was once a partner of Gome led logo light source. In 2008, LED light source solutions and products were provided for the unicycle at the closing ceremony of the Beijing Olympic Games. The "honorary commemorative certificate" and medals issued by the 2010 Shanghai WorldExpo organizing committee are special honors in the LED logo light source industry. In 2016, the lighting on the red wall side of the Forbidden City was all provided by Lanjing

lamp beads problem the lamp beads of LED lamps are divided into a string without warping and other phenomena. The lamp beads on each string are in series, and between strings, they are in parallel. Therefore, the burning of a lamp bead on this string will cause this string of lamp beads to not light up. If a lamp bead burns out in each string, the whole light will not light up. If one lamp bead in each string is burnt out, the capacitance or resistance on the driver should be considered. Burned lamp beads and normal lamp beads can be seen from the appearance,

it reduces the power loss of the power supply line and avoids the high-frequency interference pollution to the electricity. LED lamp is an electroluminescent semiconductor material chip, which is solidified on the support with silver glue or white glue, and then connected with silver wire or gold wire. The chip and the circuit board are sealed with epoxy resin around to protect the internal core wire. Finally, the shell is installed, so the LED lamp has good seismic performance. LED can directly emit red, yellow, blue, green, green, orange, purple and white light. In greenhouse or plant laboratory, it can completely replace natural light to promote plant growth

especially for the current post-80s and post-90s buyers who advocate environmental protection and pursue fashion, LED lamps are their lighting fixtures, such as choosing various styles of LED ceiling lamps, LED bulb lamps with different power, led ceiling lamps, etc. What are the benefits of using LED lights? In the s of the last century, incandescent bulbs were used at home. It was easy to break and have to change the bulbs. Sometimes I didn't pay attention to changing the bulbs as soon as the lights were turned off. As a result, I was scalded by the bulbs and my teeth cracked. Every time I was scalded, I always forgot to get started in a hurry; Because incandescent bulbs convert most of electrical energy into heat

in recent years, he has participated in the formulation of standards in a number of related industries, and has taken the lead in organizing and carrying out various industry summits and technical exchanges. Now blueview has looked forward to the trend of intelligent lighting, which will help the industry and open a new era of intelligent LED

therefore, the LED lights used for traffic control are likely to be blocked by wind and snow, resulting in traffic accidents. Lighting technical specifications and product standards are an important part of the development of the lighting industry. With the improvement of LED lighting technology, what changes will lighting technical specifications and product standards have? Or the establishment of new standards? Let's have a look! According to the "first batch of preparation and revision plan in 2019" issued by the Standards Committee as the first research base for physical property testing technology of functional film materials in China, the standards committee decided to establish and revise the standard plan "museum lighting design code"

led lamp is a kind of light-emitting diode. This kind of lamp can turn electricity into light. What is energy-saving lamp? Energy saving lamp generally refers to energy-saving bulb. The top of the energy-saving lamp is the lamp cap, and the lower part is the lamp tube structure. Which is better between energy-saving lamp and LED lamp? Second, the difference in light-emitting principle. The light-emitting principle of LED lamp: LED lamp relies on light-emitting diodes to convert electric energy into light energy. LED is basically a small LED lamp bead encapsulated in epoxy resin, so it is very small and very light
